In some cases, it might be needed to test the WPS certification by performing tests on weld discount coupons (examination items). Verifying the base metal and welding consumables compliance with the suitable requirements. Inspecting for joint cleanliness and appropriate fit-up. Making certain that the joint design and weld preparation is compliant with the WPS and appropriate welding requirements (ASME, AWS, API).




In some cases, pre-welding inspection might locate irregularities that are within code limitations but can present an issue at a later phase in manufacturing. That's why it's important for the welding inspector to be knowledgeable about the whole manufacturing process and to be experienced with the bonded devices. Evaluation throughout the welding procedure is important for spotting the weld issues and stopping an incorrect welding strategy from triggering enormous weld rejections across the entire task.
